Abstract
<P>PROBLEM TO BE SOLVED: To provide a geothermal turbine improving corrosion resistance of turbine components such as a rotor blade, a stationary blade and a turbine rotor shaft to be operated under a strict steam environment and lengthening service life by performing a secular deterioration prevention measure. <P>SOLUTION: In this geothermal turbine 10, a turbine stage 12 is constituted of the stationary blade 14 of a nozzle diaphragm and the rotor blade 15 arranged on a downstream side of the stationary blade 14. A shroud 37 is provided on each blade top part of the rotor blade 14. An eaves part 38 of a nozzle diaphragm outer ring 17 is oppositely provided at the radial direction outside of the shroud 37. A seal fin 41 projecting toward an inner peripheral surface of the eaves part 38 is provided at the radial direction outside of the shroud 37 to constitute a steam leakage prevention structure of the rotor blade top part. The eaves part 38 of the nozzle diaphragm outer ring 17 is provided with a smooth inside surface 38a. <P>COPYRIGHT: (C)2003,JPO.
